摘要:
Herein disclosed is a battery-operated, dot type recording apparatus which comprises a drive mechanism unit having its number of revolutions regulated by the output of a quartz oscillator, a circuit for connecting a d.c. power source with a meter only when a measured value is to be recorded, and delay switching means for causing the tip of a pointer of a meter to hit the recording paper at the time when that meter becomes stable. Thus, the dot type recording apparatus is so constructed of a small number of mechanical means that it can reliably operate for a long time, while having its adjustment and maintenance facilitated, with little influence from changes in circumstances.
